Personnel monitoring.

(A)
The licensee may not permit any individual to act as a radiographer or a
radiographer's assistant unless, at all times during radiographic operations,
each individual wears, on the trunk of the body, a direct reading dosimeter, an
operating alarm rate meter, and a personnel dosimeter that is processed and
evaluated by an accredited national voluntary laboratory accreditation program
(NVLAP) processor. At permanent radiography installations where other
appropriate alarming or warning devices are in routine use, the wearing of an
alarming rate meter is not required.

(1)
Pocket dosimeters must have a range from zero to two millisievert (two hundred
millirem) and must be recharged at the start of each shift. Electronic personal
dosimeters may only be used in place of ion-chamber pocket
dosimeters.

(2)
Each personnel
dosimeter must be assigned to and worn by only one individual.

(3)
Film badges must be replaced at periods
not to exceed one month and other personnel dosimeters processed and evaluated
by an accredited NVLAP processor must be replaced at periods not to exceed
three months.

(4)
After
replacement, each personnel dosimeter must be processed as soon as
possible.

(B)
Direct
reading dosimeters such as pocket dosimeters or electronic personal dosimeters,
must be read and the exposures recorded at the beginning and end of each shift,
and records must be maintained in accordance with paragraph (K) of rule
3701:1-48-23 of the
Administrative Code.

(C)
Pocket
dosimeters, or electronic personal dosimeters, must be checked at periods not
to exceed twelve months for correct response to radiation, and records must be
maintained in accordance with paragraph (K) of rule
3701:1-48-23 of the
Administrative Code. Acceptable dosimeters must read within plus or minus
twenty per cent of the true radiation exposure.

(D)
If an individual's pocket dosimeter is
found to be off-scale, or if his or her electronic personal dosimeter reads
greater than two millisievert (two hundred millirem), and the possibility of
radiation exposure cannot be ruled out as the cause, the individual's personnel
dosimeter must be sent for processing within twenty-four hours. In addition,
the individual may not resume work associated with licensed material use until
a determination of the individual's radiation exposure has been made. This
determination must be made by the radiation safety officer for industrial
radiography or the radiation safety officer for industrial radiography's
designated qualified individual. The results of this determination must be
included in the records maintained in accordance with paragraph (K) of rule
3701:1-48-23 of the
Administrative Code.

(E)
If the
personnel dosimeter that is required by paragraph (A) of this rule is lost or
damaged, the worker shall cease work immediately until a replacement personnel
dosimeter meeting the requirements in paragraph (A) of this rule is provided
and the exposure is calculated for the time period from issuance to loss or
damage of the personnel dosimeter. The results of the calculated exposure and
the time period for which the personnel dosimeter was lost or damaged must be
included in the records maintained in accordance with paragraph (K) of rule
3701:1-48-23 of the
Administrative Code.

(F)
Dosimetry
reports received from the accredited NVLAP personnel dosimeter processor must
be retained in accordance with paragraph (K) of rule
3701:1-48-23 of the
Administrative Code.

(4)
Be calibrated at periods not to exceed
twelve months for correct response to radiation. The licensee shall maintain
records of alarm rate meter calibrations in accordance with paragraph (K) of
3701:1-48-23 of the Administrative Code.
